Patent CA-2316446-A1 (CA)
Title: Method and apparatus for electrocoagulation of liquids
Inventor: POWELL SCOTT WADE
IPC: C02F1/463
Filed: 1999-02-26
Abstract: An electrocoagulation treatment device includes a plurality of spaced reaction plates disposed within a reaction chamber. A voltage is applied to selected reaction plates to create an electrical field within the electrocoagulation chamber. The plates are arranged vertically with respect to the chamber which induces a vertical flow of liquid through a device.      Gases formed in the electrocoagulation process are allowed to rise to the top of the liquid line and can be vented to the atmosphere. The solids which precipitate out of the liquid stream are carried by the liquid stream to secondary separation.  Any remaining solids can be removed as sludge through a drain in the bottom of the device. A foam cover is provided to isolate the electrical connections of the plates from moisture. The top cover is provided to isolate the chamber for safety purposes. The device may be manufactured as a large industrial unit, a portable unit or a unit adapted for use within the home. The device may be operated in a pressure controlled environment, thus eliminating the need for a pump when the liquid stream is already pressurized. The voltage and amperage of the electrical field within the reaction chamber may be adjusted as necessary by placing selected reaction plates in electrical contact with the voltage source. The incoming line voltage itself may be kept at a constant which eliminates the need for a separate transformer. The reaction plates are easily removed from the reaction chamber and may be replaced individually or as a set.

Title: Pull handle with interlocking mounting mechanism for wet/dry vacuum appliance
Inventor: HOLSTEN STUART V
IPC: A47L9/32
Filed: 2001-01-10
Abstract: The present invention is a handle used for pulling a wet/dry vacuum appliance and a mechanism for securely mounting such a handle to the lid of the vacuum. The mounting mechanism is designed for ease of assembly and reduced fastener cost. The handle is attached at two of its four attachment points by inserting journals molded into the sides of the handle into open bearing pockets molded in handle receiving recesses on the lid of the vacuum. The handle is then rotated into place and secured at the remaining two attachment points with suitable fasteners, such as screws. In certain embodiments of this invention, when the handle is rotated into position for attachment a locking slot in the bottom surface of the handle engages a rib provided in the handle receiving recess of the lid. This rib guides the handle as it rotates, prevents the journals from sliding back out of the bearing pockets, and locks the handle into the proper position for insertion of the fasteners.
Patent CA-2334542-A1 (CA)
Title: Method and device for dropping optical channels in an optical transmission system
Inventor: AINA STEFANO
IPC: H04B10/291
Filed: 1999-06-07
Abstract: The present invention proposes a method and a device to add and drop optical  channels in an optical transmission system (1) in which a multi-channel optical signal is transmitted into an optical fiber line (300). The OADM (Optical Add/Drop Multiplexer) device (695; 695') includes an optical splitt er (673) receiving an input signal which includes at least one sub-group of the  whole channels. Optical splitter (673) has an unbalanced power splitting rat io - in the range 60:40 to 90:10 - for feeding a main power fraction (60 % to 9 0 %) of said input signal to a first output port and a secondary power fractio n (40 % to 10 %) of said input signal to a second output port. The secondary power fraction defines a drop signal and is received by a demultiplexer (680 ; 682) where drop channels are extracted. The main power fraction defines a pa ss- through signal which is conveyed from the optical splitter (673) to an optic al coupler (674) where the pass-through signal is coupled with an add signal, coming from a multiplexer (681). Optical coupler (674) has an unbalanced coupling ratio - in the range 60:40 to 90:10 - so that it generates an outpu t signal prevalently constituted by the pass-through signal. Cascaded Bragg gratings (678), positioned between the optical splitter (673) and the optica l coupler(674), selectively retro-reflect the drop channels from the pass- through signal, and an optical isolator (679), positioned before the optical  splitter (673), suppresses the retro-reflected drop channels.

Abstract: A method for assembling interior vehicle trim parts including panels and components in which two trim parts are disposed adjacent one another and in which a bead (12) of buffer material is disposed between mating surfaces of the two trim parts. The bead (12) is included to reduce noises such as buzzes, squeaks and rattles produced by contact and relative motion between the first and second trim parts at their mating surfaces. The bead (12) is mechanically locked into a recess in one of the mating surfaces. The bead (12) is mechanically locked to a mating surface (16) by forming a recess (24) in the mating surface (16) then applying buffer material in the recess (24). The buffer material is applied in such a way as to form a bead (12) of buffer material on the mating surface (16). The bead (12) is allowed to mechanically connect to the first trim part (16) as a result of the hardening of the buffer material within the recess (24).
